Nigeria is endowed with a good reserve of wood (8). Depending on the climate of the region and the size of the mill, sawing operations may be performed outdoors or indoors (2). In Nigeria, most of the sawmilling processes are performed outdoors. Workers in outdoor sawmills are at added risk of chronic exposure to ultraviolet radiation (290–400 nm), as are other outdoor workers (10). Thus, they are at risk of developing ocular disorders, such as pterygium, pingueculum, dry eyes, senile cataract, and age-related macular degeneration (11,12). Those in the tropics have a greater risk because of the hot, dry, sawdust- filled environment. Hence, it is necessary to protect the eyes by wearing large goggles with side shields. These workers are also at risk of bacterial and fungal ocular and orbital infections (6).
